Photonic Band Gaps and Resonance Modes in 2D Twisted Moiré Photonic Crystal
Photonics, 2021 The study of twisted bilayer 2D materials has revealed many interesting physics properties. A twisted moiré photonic crystal is an optical analog of twisted bilayer 2D materials. The optical properties in twisted photonic crystals have not yet been fully

Spatiotemporal Photonic Crystals
Conference on Lasers and Electro-Optics, 2020 We study photonic systems periodic in both time and space - spatiotemporal photonic crystals, and find that their bandstructure contains both frequency and momentum bandgaps. When the two types of bandgaps coincide, anomalous bandstructure is observed.

Scientific Reports, 2017 AbstractWhen space (time) translation symmetry is spontaneously broken, the space crystal (time crystal) forms; when permittivity and permeability periodically vary with space (time), the photonic crystal (photonic time crystal) forms. We proposed the concept of photonic time crystal and rewritten the Maxwell’s equations.
